Welcome to the Predator Ecology Lab!
Since 2008, as part of the Wildlife Science Program in the University of Washington's School of Environmental and Forest Sciences, we have sought a better understanding of how predators influence their surroundings by interacting with one another and their prey. Much of our work also seeks solutions to the challenges of large carnivore conservation and management in a changing world.

October 16 and 24, 2017: Congratulations to Clint Robins and Lauren Satterfield for well received talks respectively titled, "Investigating the effects of urbanization on cougar foraging ecology along the wildland-urban gradient of western Washington" and "Competition in the forest: understanding ecological relationships between cougars and wolves in eastern Washington". Clint's talk was part of the School of Environmental and Forest Sciences Wildlife Seminar (ESRM 455, SEFS 554), whereas Lauren's featured in the 50th Anniversary Symposium of the Washington Cooperative Fish and Wildlife Research Unit.
October 3, 2017: We would like to direct your attention to a new paper in Proceedings of the National Academy of Sciences of the United States of America titled, "Extinction risk is the most acute for the world's largest and smallest vertebrates". Led by long-time collaborator Professor Bill Ripple and also involving former PEL post-doc Dr. Thomas Newsome, the paper shows that a variety of stressors are truncating the vertebrate size spectrum at both ends. Thanks, Bill, for including us in this exciting work!
August 8-9, 2017: Thank you to the Pacific Science Center and Central Cinema for inviting us to participate in Science and a Movie presents Jaws!
The Science and a Movie series offers moviegoers the chance to learn about research that is related to classic films. As part of the two night event, I (AW) got to give a talk titled, "Tiger sharks keep seagrass ecosystems healthy by scaring sea turtles" and then fielded questions from the audience about shark biology and the portrayal of sharks in cinema after the screening of Jaws (one of my favorite movies). Special thanks to Anna Ferrario of the Pacific Science Center for making all of the arrangements!

Happily, Clint will be continuing on in the PEL to complete his doctorate, which will address the influence of western Washington's wildland-urban gradient on cougar hunting behavior and interactions with black bears. His PhD research will be supported by a $20,000 grant from Conservation, Research and Education Opportunities International (CREOi). Excellent work all around, Clint!
May 23, 2017: We also have a new paper to report, published today in Nature Communications! The article ("Top predators constrain mesopredator distributions") reveals that large carnivores such as gray wolves and dingoes need expansive ranges to suppress smaller competing predators including coyotes and red foxes. The paper is covered here by the University of Washington.
May 23, 2017: Congratulations to Lauren Satterfield, whose proposal to the Washington Department of Fish and Wildlife Aquatic Lands Enhancement Agreement (ALEA) program titled, "Assessing wolf-cougar interactions and impacts in Washington" was funded today to the tune of $16,200. The grant will support volunteer involvement in her field work, which this summer will entail visiting cougar kill sites in eastern WA (among many other things!).
May 19, 2017: We are also pleased to pass along that Erin Strand, another of our undergraduate interns, presented a poster titled, "A test of the mesopredator release hypothesis in a multi-use landscape" at the recent Undergraduate Research Symposium in Mary Gates Hall. Great job, Erin!
May 18, 2017: Happy news to report from Hannah Booth, who was just received a prestigious Xi Sigma Pi Undergraduate Research Award in the amount of $700 for her proposal titled, "The relationship between wildfire and the cascading impacts of predators on plants"! Hannah has been working with Apryle Craig as an intern in our lab and will now be able to travel to our field site in eastern Washington to examine the impacts of the historic fires of 2015 on wolf-prey-plant interactions. Way to go, Hannah!
April 26, 2017: Continuing the positive momentum, we've just published another paper in the journal Biological Conservation, this time on the impacts of domestic dogs on threatened wildlife. Led by Tim Doherty (of Deakin University in Melbourne, Australia), the paper is the most comprehensive survey of the effects of feral and owned dogs on wildlife to date, and highlights their impacts as an under-appreciated conservation challenge.
April 5, 2017: We just published a paper in Bioscience ("Making a new dog?") examining the possibility that increasing exposure to human foods and other resources might disrupt ecological roles of large carnivores and, in the case of wolves, reinitiate the early stages of domestication. Led by former PEL post-doc Thomas Newsome, the paper has already received considerable media attention (e.g., https://oxfordjournals.altmetric.com/details/18533051/news).
March 28-31, 2017: We are proud to have had Apryle Craig and Laurel Peelle represent us at the recent Joint Meeting of the Washington Chapter of the Wildlife Society and the Washington State Society of American Foresters in Yakima. Apryle presented a poster titled, "Do recolonizing wolves impact deer hunter success?", and Laurel presented a talk titled, "Predator species identification from saliva at kill sites with limited remains".
March 29, 2017: Congratulations to Carolyn Shores, who today successfully defended her dissertation proposal titled, "Ecological effects of disturbance on carnivore and ungulate communities in northeastern Washington state" and thereby advanced to candidacy!
March 25, 2017: Lauren Satterfield and Apryle Craig attended Comscicon, a 2-day science communications workshop.
